Test set-up for bifacial modules

Bifacial modules are calibrated in the newly developed test set-up. Bifacial modules make use of irradiance on the front and back side.

Flasher measurement at the laboratory “CalLab PV Modules”

For manufacturers and investors, it is crucial to know precisely the performance of their modules. The measurement accuracy for precision measurements stands at unprecedented 1.6%.

Module Characterization


In our field of work Module Characterization, we offer the following services:

Our accredited calibration laboratory, CalLab PV Modules, unites the highest level of scientific know-how with cutting-edge measurement technology. Renowned module manufacturers, EPCs and investors with the highest quality requirements are among our clients, all of whom value our longstanding experience and global reputation in the field of module calibration.

We offer expertise ranging from precisely calibrating single cells and modules through to complex, customized tasks, such as accurately calibrating bifacial modules. With an uncertainty range of just 1.6%, our measurement accuracy under standard test conditions outranks that of our international competitors while our quality assurance services go far beyond. We provide support for full characterization of modules in accordance with the energy rating standard IEC 61853-1 and for quality benchmarking with individual testing procedures.

Our goal is to gain a detailed understanding of our clients’ requirements and offer tailored solutions.

In our accredited Lab CalLab PV Modules at Fraunhofer ISE, we offer a comprehensive range of services in the field of Module Characterization.
